Answer
$$-27x^6$$
Work Step by Step
First, we raise each factor to the power outside the parentheses:
$$((-3)^3)(x^2)^3$$
Evaluate the coefficient first:
$$-27(x^2)^3$$
We use the power rule, which states that when you raise a power to a power, you can multiply the two exponents together:
$$-27x^{(2)(3)}$$
Multiply the exponents:
$$-27x^6$$
